Over time, it has been found that there are relatively only a few psychological studies related to the importance of environmental education in primary classes in Romania. Some of the topics that could be discussed at this level could be grouped into the following categories: -the relationship between man and nature at children's;children's competences related to geographical space, local horizons;-geographical / spatial preferences for children;-recycling possibilities proposed by children,-children's reactions linked to environmental disasters and nuclear weapons. We conducted an experiment at the school from Poiana Codrului, Satu Mare County, on a number of approximately 180 children with the average age of about 12 years. The following aspects were tested: Human-Nature Relationship, as well as Psycho-geographic Competencies developed at children's. The children were put in the situation of a fictitious "outdoor center" case, in the middle of nature, where they had to motivate their choices. The used didactic methods were: participation, play, project, etc. Thus, analysing the expectations presented in Piaget's theories of cognitive development, the hypothesis that at the end of primary classes the children's are able to make a deeper and more complex analysis of environmental issues centered more on causal problems is confirmed. The study attempted to emphasize at the same time another aspect related to the various forms of environmental organization in the case of children's.
